My battery died and after I charged it the map screen doesn't work anymore.
there's no home screen anymore. Just audio and climate screen works.
How do I get my map screen to work again guys?

Thank you

 

use your iPhone.

j/k, I'm 100% sure you need to put your navi disc in.

 

Reset the ecu

 

Sounds like the Navigation computer/DVD Player is now powering up. Check the fuses related to the navigation and the connection in the back of the navigation unit in the trunk.

If it was just the disc it would be giving a disc error on the screen.
